Abstract (en)
[origin: EP1424635A1] The present invention relates to a non volatile memory device architecture, for example of the Flash type, incorporating a memory cell array (3) and an input/output interface (2) to receive memory data and/or addresses from and to the outside of the device. The interface (2) operates generally according to a serial communication protocol, but it is equipped with a further pseudo-parallel communication portion with a low pin number incorporating circuit blocks (4, 5, 8) for selecting the one or the other communication mode against an input-received selection signal. <IMAGE>
